Here’s a rather brilliant and subtle decorating idea: British artist James Hopkins carefully arranges mundane objects into artwork with “hidden messages.” I’m not quite sure how “hidden” the skulls are, but I love the arrangement.

This would be a fun project if you’ve got a bare wall to cover. Get a cheap bookshelf and arrange random knick-knacks in a similar skull pattern, collecting additional objects over time to fill in any gaps. Simple but extremely effective.
